Abstract
Although the model we studied is oversimplified, it illuminates the dynamical evolution of two Fermi gases which are brought into contact. The dissipation introduced by a residual two-body interaction was illustrated with the Wigner function and the macroscopic variable NL which counts the number of particles in one half of the system.
The origin of the small variances in TDHF was discussed, and the results of the model study lead to the prediction that inclusion of short-ranged collision terms in mean-field theories will not increase essentially the fluctuations in the macroscopic variables.
